I agree that "agile" teams that group people by specialty are clueless. Done right, the teams are, as you suggest, cross-functional. That was the original intent for the people who coined the term Agile, but much of that has fallen by the wayside as larger organizations decided Agile was fashionable and consultants rushed in to sell them 3% dilutions of XP or Scrum.
That's a great writeup! I know exactly how you feel except my disappointment was doubled, because I was a hybrid developer/designer for years before completing the switch from developer to designer and I lost the faith in both agile and UX at about the same time.
I wish I had the courage to write up my disappointment like you did, but I'm happy that I've moved on to a meta-process of borrowing from different techniques as needed.
